本文实例讲述了C#发送内置图片html格式邮件的方法。分享给大家供大家参考。具体如下：
下面的代码用于发送html格式的邮件，并且可以将图片附加到邮件一起发出
MailMessage m = new MailMessage();
m.From = new MailAddress("ir@phpstudy.net", "Raja Item");
m.To.Add(new MailAddress("su@phpstudy.net", "Sekaran Uma"));
m.Subject = "html email with embedded image coming!";
// Create the HTML message body
// Reference embedded images using the content ID
string htmlBody = "<html><body><h1>Picture</h1><br><img src=\"cid:Pic1\"></body></html>";
AlternateView avHtml = AlternateView.CreateAlternateViewFromString
(htmlBody, null, MediaTypeNames.Text.Html);
// Create a LinkedResource object for each embedded image
LinkedResource pic1 = new LinkedResource("pic.jpg", MediaTypeNames.Image.Jpeg);
pic1.ContentId = "Pic1";
avHtml.LinkedResources.Add(pic1);
// Create an alternate view for unsupported clients
string textBody = "You must use an e-mail client that supports HTML messages";
AlternateView avText = AlternateView.CreateAlternateViewFromString
(textBody, null, MediaTypeNames.Text.Plain);
m.AlternateViews.Add(avHtml);
m.AlternateViews.Add(avText);
// Send the message
SmtpClient client = new SmtpClient("smtp.phpstudy.net");
client.Send(m);
希望本文所述对大家的C#程序设计有所帮助。
